Integrity

Three anti-gaming detectors run against your scored sub-sessions, guarding the score against inflation or gaming. Each raises a flag on the sub-session when something looks off.

These guards run in the background. The one you see directly is Fragmentation merge, counted on the score hub’s Merges card. Whenever a guard is the reason a sub-session left your score, the exclusion reason on its Sessions row says so.

The three detectors

Flag	What triggers it
Substance floor breach	A sub-session was scored despite too few turns, no edits, or no mutating tool calls.
Median substance outlier	A sub-session sat far below the team’s typical substance level for that intent.
Fragmentation merge	Several short sub-sessions inside a short window were merged into one — looks like a single task was split across many starts.

Good to know

• Flags don’t cut your score directly — they just mark sub-sessions that may be worth a look.
• If Fragmentation merge shows up often on the hub’s Merges card, try keeping a task in one sub-session instead of restarting Claude Code mid-task.
